RE: comcast spam policies

From: doug(a)safeport.com > > The current comcast policy seems to be to backhole mail > servers at random. This is true. We do mostly ecommerce hosting and often our customers have their own dedicated servers blacklisted from sending email notifications of new orders to their home comcast addresses. We have to request unlisting regularly. David

No DNS operations BOF at NANOG39
by Keith Mitchell 06 Feb '07

06 Feb '07

Unfortunately due to not enough potential speakers, and pressure on BOF slots in the program, we have decided to not have this BOF this time around. My apologies for this - a number of potential speakers indicated they were preparing relevant work which would be more ready to present next time around, so hopefully at NANOG40.. If anyone would still like to have a DNS operations discussion in Toronto, I'm happy to facilitate this on an ad-hoc/informal basis. just drop me a note. Keith Mitchell OARC Programme Manager

TorIX Tours on Tuesday February 6
by Joe Abley 06 Feb '07

06 Feb '07

[Apologies for the following non-operational content; if you are not coming to Toronto next week, hit delete now] For those attending NANOG 39 in Toronto next week who don't already see enough generic data centre space in their normal work week, there will be a TorIX tour on Tuesday February 6, some time after the last BOF/Tutorial finishes. There's a limit to the number of people we can practically haul through building security without causing trouble, so first-come, first-served. If for some bizarre reason there is an unexpectedly large number of people who think touring 151 Front is the right way to spend a Tuesday evening, we might try and do two trips, find people to open more than one suite, etc. If you're interested, sign up here: http://nanog.cluepon.net/index.php/NANOG39TorIXTour Joe

what the heck do i do now?
by Paul Vixie 05 Feb '07

05 Feb '07

bear with me, this appears to be about DNS but it's actually about e-mail. maps.vix.com has been gone since 1999 or so. mail-abuse.org is the new thing. i've tried just about everything to get traffic toward the old domain name to stop... right now there's a DNAME but it made no real difference. i've taken the maps.vix.com domain away. i've set its NS to "localhost". i've put long TTL's on both good and bad data. the traffic continues. clearly this is my pennance for starting MAPS, and i hear you giggling about it, but i need some advice. once upon a time, someone more insane than myself wanted to close an RBL and did so by replacing it with a wildcard entry. we all hated that since it caused a lot of mail to bounce. (all mail that would otherwise have been received by that RBL's subscribers, in fact.) it did however have the effect of causing the subscribers to reconfigure their mailers to stop querying the now-dead RBL in question. what's the current thinking on this? oh and even though this isn't about bgp i can put some numbers in so that it will seem on-topic. out of 100K DNS queries received by a vix.com nameserver (which is about five minutes worth), here are the toptalkers for maps.vix.com. (and we all know by now that public shaming and notification won't work, i'm not sure why this is relevant, but it looks good, so here it is.)

RE: broken DNS proxying at public wireless hotspots

>If so, how do you configure your client operating system of choice to use the novel, un-proxied ports instead of using > port 53? * Set up the profile, to your house/work/etc, of your favorite SSH client to forward port 53 local to port 53 on your remote machine. * Make sure your SSH Profile connects to your house/work/etc via IP, not name * make sure there is some sort of DNS server running on the target of your SSH session * make sure your SSH server supports forwarded ports * connect to your house/work/etc. * repoint your local DNS client config to 127.0.0.1 * browse at will * (don't forget to undo this later or risk losing your sanity....) Same type of config works great for HTTP (with squid, and browser proxy settings) etc..
